Question about 2007 Triumph Triumph Bonneville

1 Answer

Save our bonneville

If anyone can provide me with info I would greatly appreciate it. Here's what happened: My husband performed an oil change, lubed the throttle and clutch cables on our 2005 Bonneville. When he did the oil change he used car engine oil rather than an oil specially designed for motorcycles. On the second ride after the oil change the bike starting acting weird: backfiring, surging forward and then stalling continuously, but always restarting immediately. When this happened he contacted a triumph dealership and spoke with a mechanic there and was told that he shouldn't have used the car oil and to get it out. So he performed another oil change and filter change too. The bike backfired, surged and stalled for the first twenty minutes, but then all symptoms completely disappeared while riding for another two hours. We went to a family function, rode for another twenty five minutes without a problem. We went home and took the bike out an hour later for another ride and it was fine for the first ten minutes, but then the original symptoms reappeared as bad as ever. We rode it on two other occasions and it remained troublesome. We have since emptied the gas tank and cleaned the filter and checked out the carb which seems spotless. Any suggestions would be appreciated because I am insistent on keeping this bike, while my husband is not.

Sounds like the throttle cables need to be looked over .( he get everything back to where it was before the lubing?)as one may be out of sync with the other. the oil change has NOTHING to do with the sputtering and surging ,stall .it would only apply if the clutch was slipping and that would make the bike rev with the car oil.

I cant find how to check the oil level on my 83 rm 250 anyone know how to or where on it to check

Look around the clutch cover for a screw or bolt somewhere around the 4 o'clock position(not a mounting bolt, it will actually go thru the side of the cover). Remove it, and with the bike level oil should be at the level of this hole.
If you can't find the oil level hole, or want to be sure, just change the gear lube. There is a drain bolt in the bottom, and the correct amount of oil is stamped on the cases in cc's or cm3. Reinstall drain bolt and measure out the correct amount of good 10-40 oil and put it in.
The gear lube should be changed every 10 hrs of operation, and it's cheap insurance to keep your clutch and tranny in good shape. Good luck!

Just bought an 02 Bonneville that has been sitting for 2 years in a heated garage with a small amount of fuel in the tank. Any precautions other than fresh gas and battery before I attempt to start the...

If it has been standing for a long time the fuel could have evaporated from the carb. Evaporated fuel leaves behind a powdery residue that could clog the jets in the carb which would make for hard starting and poor performance. If started and this happens, run some carb cleaner through the engine. Also, shaft seals tend to harden, so be prepared for some oil seepage. If luck is on your side then you wont have a single problem.

What kind of oil should i use for a 1999 honda cbr 600 f4

10w-40SJ Honda Motorcycle oil only.
Would appreciate a rating thanks! Change your oil more frequently if you ride the bike hard or especially if you ride the track like i do...i change my oil before and after a race!! and i"ve put 30k "extremely" hard miles on this engine and still performs well for a bike with 50k on the odometer! my bike is the very first 87 CBRF1 Hurricane.. i also have an 88 with only 16k on the odometer! Hondas are bullet proof, but the oil is the Key because everytime you miss-shift and grind a gear the same gear oil is used to lube the top half of the engine.

Gearbox is shifting difficult. i have to shift it a few times before it will go into gear. It happens when i shift over to the 3rd gear and up. Hope you recognize this problem. Thanks Tjeerd de Ree

Howdy: Yamaha's are known for great transmissions but sometimes they get sticky. Before you tear it down, you can try what I do with my high mileage bikes. Drain engine (trans oil) after engine is warmed up.
Then try Yamaha Lube Performance - Semi -Syn 10/40. This could help, it has me. Good luck - Ride safe - Doug

Clunk from engine/crankcase area

Try at stationary under heavy load with clutch to isolate, sounds serious, I'd check all transmission connections are right before riding again.

Bonneville T100 Gear Change

Do check if not drain and refill the gear box, but check with your dealer that it will not affect your warranty. a little self help may prevent time consuming and inconvenient repairs at this stage, but remember gears are clunky and come in for a lot of abuse, reliable as they are.
